Predict Snowfall Totals


Absolute Humidity

Recommended Posts

This was my first call as of yesterday late afternoon. (posted in NW thread yesterday) As of now I see no significant reasons to alter it much. As with most winter events in this area there will a few surprises on the good and bad side but all and all you can pretty much broad brush the area as 5-10". A few areas may fall short of that and a few areas may exceed it but I suspect about 75% of us fall in that range.

this map makes sense.

 

Thank you, I think a lot of people are going a bit over board with totals. Honestly, I don't see the city getting 10". I see maybe, maybe, eastern LI getting a foot, but that will be very isolated. I'm not really liking the whole ratios idea either.

Most surprising outcome to me was how well South Jersey, even down to Cape May and the Delaware Bay, Delaware, and SE PA (around Philly) did, as most were predicting 2-4" for those folks or less - Philly, with 9", had more than all of the metro NYC major stations (EWR/LGA/JFK).  And, of course, most galling was that my hometown in Gloucester County, Washington Twp, had more than I did here in Metuchen (8.1" to 7.0"), which was not supposed to happen, lol.

Yeah I think the heavier precip and better ratios were progged to be further north but it did seem like south jersey was definitely under forecast considering it was plenty cold enough and was certainty plenty of moisture

Yeah, they got crushed again. It's their winter too. Snowfall averages so far this winter are remarkably uniform from South Jersey through Conn.

The models were placing parts of SJ in the possible areas for an inverted trough.

But they were never forecast for more than 2 - 4 until the event was in progress. The Norlun did happen but it was weak and about 50 miles more north than progged. It began around 7am and ended around 10am. It aligned itself from Monmouth county, northeasterly encompassing most of Long Island. It did give me an additional inch or so, more for Long Island.

My guess:

 

-EWR: 7"

-Central Park: 8"

-JFK: 8"

-FRG: 8.5"

-ISP: 9.5"

-HPN: 8.5"

-BDR: 10"

-TEB: 8"

-MTP: 8"

-Upton: 9.5"

 

6" line should be around New Brunswick SE to hugging the NJ coast along the Garden State Parkway. 10" starts northeast of Bridgeport. Montauk isn't usually a jackpot zone, and I could see the north shore receiving some enhancement from the Sound at the end. I could see spots like around Syosset over to Coram taking the prize.

Verification-quite a range of totals.

-EWR: 8.5"

-Central Park: 6.4"

-JFK: 7.9"

-FRG: Closest spots are Plainview and Melville which are 10.5" and 12.0" respectively

-ISP: 11.2"

-HPN: 8.0"

-BDR: 4.7"

-TEB: Average in Bergen County seems to be around 6"

-MTP: Closest is Bridgehampton with 9"

-Upton: 11.4"

 

Overall I'm surprised that the South Shore seemed to receive higher totals this time. I thought the Sound enhancement would do more for the North Shore but overall it was a very respectable storm for all. I had concerns about a shadow zone developing over CT between the heavy snow over eastern NE and the snow here from the coastal low and inverted trough. That trough really made this a top tier event by preserving the falling snow-that's how we received the 10-12" totals we did in some spots. I thought the odds of me making it to 10" were fairly low but I think I ended up with about that much. It was a very fun night, that's for sure.

This is what I posted earlier tonight on my friend's board

CNJ, NNJ, NEPA 5-9"

NYC (5 boroughs) in 6-10"

Nassau, W Suffolk, NJ shore, HV (HV due to ratios) 7-12"

C and E Suffolk 8-14"

I basically verified ..HV was generally near or just below my lower range. I think it was a good call

I'm thinking more of a 5-7" snowfall through the NYNJ metro area. I went with the higher amounts but it is very possible many areas only get to around or near 5". Long Island amounts should quickly be up in the 8-12" range, as with SNE 10-15". I believe some areas in south and central NJ will beat out NNJ and NYC. I'm thinking 6-9" there

NYC : 6.5"

EWR : 6"

Freehold : 7.5"

Islip, NY : 9.5"

Medford, NY : 10.5"

Boston, MA : 10"

Philadelphia, PA : 5.5"

Overall I didn't do too bad here....but I feel I had the right idea. I actually believe EWR's official # of 8.5 is really quite inflated. I ended up with just barely 6" a few miles north of there. I measured in several spots and after Having seen dozens of 6"+ storms, you can sometimes just tell.....and this one was barely there. In regards to the other snow totals in here, the idea of there being more snow than NWS/other outlets were first forecasting in southern areas, was correct. The 10-15" in SNE was correct for the most part, aside from the 16-23" lollipops. The 8-12" on Long Island came out pretty well....but of course I didn't really "pull the trigger" with the Philly call amount...but the 6-9 forecast for south central NJ was pretty good.

Overall....I give myself a B-

:P
